Most criteria are met, the product well:
+ It is adequately sealed against dirt
+ The reception is not impaired by the shell
+ Weight is not felt at the foot
+ Stop Button to operate through the shell (which I have used this only at the beginning)
+ Easy to change
The only drawback in my opinion is the temple, he loses with me regularly twists the grip on the housing and the sensor. In two cases, I have already lost it and was then informed by the Ipod that no contact exists ... especially ugly you have to interrupt the run to look for the little thing. With Tape over this problem can be easily fixed but, however, the manufacturer could improve quite arresting.
Thus, the good middle, three stars.
I have in the meantime changed to Marware SportSuit Sensor Case for Apple iPod in combination with Nike athletic shoes, this holds great and is similar functionally (moisture protection not tested).
